Application filed June 2,

' for compressing the spring, in order t at a pin which holds the spring on the shaft may be removed during repair work; and it is an objector this invention to provide anchoring means, associated with a yoke or head shaped to bear against the spring and having a slot forming a clearance for the pin; the said device being effective to compress the spring and release the tension on the pin, as stated, in order that the pin may be removed. without injuring the parts of the device or preventing their dissociation, as would be the case if the spring were allowed to act.

An object of this invention is to provide means by which the spring compressing element is adjustable and by which it may be heldv in different positions through the action of a screw by which the spring compressing element is moved with relation to the jaws.

A still further object of this invention is to produce a clutch spring releasing member which can be readily applied to or removed from the shaft having the spring with which it coacts, and in which an adjustment is provided to allow for variations in sizes or the like.

lVith the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a view in elevation.

' In these-drawings 5 .ing a screw threaded aperture 6, the said head terminating curved formation, as shown, having an inturned end terminating in proximity to a, line through nalaxis of the aperture 6 and having diverging jaws 8 and 9 formed thereon, the

outer edge of which is curved, as shown at 10. The head 5 has an arm 11 connected to it through the medium of a pivot 12, and the said arm has an inwardly turned end terminating in the jaws 12and 13, similar in construction to the jaws 8 and 9 and intended to coact therewith during the,

operation of the devlce.

screw l-is threaded through the aperture 6 of the head and it is providedwith a head 15 and a suitable operating handle 16 by which the screw is turned, the said denotes a head hav-' in an" arm 7 which is of the said arm the longitudi' screw having ayqke 1 7 swiveled on its end between the arms. yoke is such that 1t will bear against the end of the clutch spring of the Chevrolet automobile, and the jawsof the arms embrace the sh'att in which the spring is seated, so that when the screw is advance through the head, in compressing'the spring of the clutch to relieve its tension from the pin, in order that the same may be removed to disassemble this part of the automobile.

spring 18 has one end anchored to the arm 7 and The configuration of the hold. the jaws other. I

The yoke 17 has a pin 19 projecting from it on which a yokeibrace 20 is oscillatable, the said yoke brace having an angularly disposed end 21 partially embracing the threaded to i it will result the opposite end anchored to the arm 11, andthesaid spring 18 is operative to normally exert a pull on the arm 11 toin operative relation to each arm 11 for holding the movable arm in ad- 1 usted position with relation to the arm while the device is being operated to compress a spring. From the drawing, it will be seen that when the an, inspection of a arm 11 is moved into cooperative relation with the arm 7, the yoke may be oscillated on its pivot to cause the angnlarly disposed end 21 to bear against it after the jaw of the arm 11 is properly seated with relation to the element with which it coacts while the screw is being advanced, and of course this relation of parts prevents any disarrangement of the parts which might interfere with the successful operation of the device.

I claim:

1. In a clutch spring compression device for automobiles, a head having a rigid and a pivoted arm, each having an inturned end terminating in a jaw, one of which coacts with the other, a yoke, means for advancing the yoke with relation to the jaws of the arms, and means for holding the pivoted arm in operative relation to the rigid arm and the yoke. 7,

2. In a clutch spring compression device for automobiles, a head having a rigid arm and a pivoted arm, the said arms having inturned ends terminating in jaws, the said head having a threaded aperture therein, a screw threaded in the aperture of the head, a yoke swiveled on the inner end of the screw, said yoke having a slot therein to form a clearance for a clutch spring pin and the said yoke being adapted to bear against the end of said spring, a yoke brace pivoted to said yoke and having an extension partially embracing and bearing on the pivoted arm for retaining the parts in operative relation to one another.
